What materials are used for polishing glass?

Polishing glass uses polishing liquid or polishing powder. The main component of polishing materials is cerium oxide, with polishing powder being cerium oxide polishing powder, and polishing liquid being a water-soluble polishing agent free from sulfur, phosphorus, or chlorine additives. Both materials have moderate hardness, enabling fine polishing of glass with excellent results. Polishing can remove surface patterns, scratches, and other imperfections from glass, improving its transparency and refractive index, thereby restoring the glass to its original clarity. Before polishing, it is necessary to clean the glass surface of impurities to avoid secondary damage during polishing. Then, apply the polishing liquid to the polishing machine, ensuring uniform polishing force and appropriate pressure, with slow grinding to guarantee the desired effect.

What are the body dimensions of the Audi Q5?

Audi Q5's length, width, and height dimensions are 4629mm/1898mm/1655mm, which are official data. The length of the Audi Q5 refers to the distance between two vertical planes perpendicular to the vehicle's longitudinal symmetry plane and touching the outermost protruding parts at the front and rear of the car; the width refers to the distance between two planes parallel to the vehicle's longitudinal symmetry plane and touching the outermost rigid fixed protruding parts on both sides of the vehicle; the height refers to the distance between the highest point of the vehicle and the vehicle's supporting plane. The turbocharged engine of the Audi Q5 has a maximum power of 169 kW and a maximum torque of 350 Nm. This engine's maximum power speed ranges from 4300 to 6000 rpm, and the maximum torque speed ranges from 1500 to 4200 rpm. It features in-cylinder hybrid injection technology and uses an aluminum alloy cylinder head and cast iron cylinder block. This engine is paired with an automatic transmission (AT). There are national regulations regarding vehicle dimensions. According to the national standard "GB1589-89," the total width of a vehicle does not include side mirrors. The limitation on vehicle width is to provide sufficient lateral clearance for overtaking between adjacent lanes. This means that in the national standard, the significance of vehicle width data lies in ensuring enough space during overtaking, preventing accidents due to excessive width or situations where road markings are narrower than the vehicle's width. Additionally, national regulations stipulate that the total width of a vehicle must not exceed 2.5m to meet the usage requirements of public roads.

What does oil emulsification mean?

Oil emulsification refers to the appearance of white emulsion-like substances on the engine oil filler cap. Causes of oil emulsification: Oil emulsification occurs when water enters the engine oil, which can happen due to poor sealing performance of the engine oil filler cap or cracks in the cylinder block or gasket. If oil emulsification is observed, it is crucial to replace the oil immediately and identify the source of water ingress. Engine oil, also known as engine lubricant, serves multiple functions including lubrication and friction reduction, auxiliary cooling, sealing and leakage prevention, rust and corrosion protection, and shock absorption. Engine oil consists of base oil and additives. The base oil is the primary component, determining the fundamental properties of the lubricant, while additives enhance and compensate for any shortcomings in the base oil's performance. Precautions for oil replacement: Regular oil changes are necessary. Different types of oil should not be mixed. It is advisable to purchase high-quality fully synthetic oil. Fully synthetic oil should be replaced every 8,000-10,000 kilometers, semi-synthetic oil every 5,000-8,000 kilometers, and mineral oil approximately every 5,000 kilometers. Regularly clean the engine filter and replace the oil filter. After adding new oil, sludge and carbon deposits on engine parts disperse into the oil, causing it to turn black over time. The need for replacement should be determined based on the oil's viscosity rather than just observing its color change. Insufficient oil can lead to inadequate lubrication and cylinder scoring, while excessive oil can reduce vehicle power and increase fuel consumption.

What is the fuel consumption of the Venucia T70?

There are 3 models of the Venucia T70 currently on sale. Among them, the 2020 2.0L CVT Jingyue Sport Edition - China VI, equipped with a 150 horsepower engine, has an NEDC fuel consumption of 7.3L per 100km. The 2020 2.0L CVT Jingrui Edition - China VI and Jingxiang Edition - China VI, both equipped with 150 horsepower engines, have an NEDC fuel consumption of 7.2L per 100km. The fuel tank capacity is the same for different models of the Venucia T70. The distance that can be covered with a full tank of fuel is as follows: Models equipped with a 150 horsepower engine and NEDC fuel consumption of 7.3L or 7.2L per 100km have a fuel tank capacity of 65L. The distance that can be covered with a full tank is 65/7.3*100=890km; 65/7.2*100=903km. The fuel consumption of a car is directly related to five major factors: driving habits, the car itself, road conditions, natural wind, and ambient temperature. Specific factors that can increase fuel consumption are as follows: Driving habits: Aggressive driving, such as sudden acceleration, frequent overtaking, and not easing off the throttle before a red light, can increase fuel consumption. The car itself: Cars with larger engine displacements generally consume more fuel than those with smaller displacements because larger displacements usually mean higher power, requiring more gasoline to burn and perform work. Heavier cars also consume more fuel because greater weight requires more driving torque. Road conditions: Driving on dirt roads, muddy roads, soft surfaces, or mountainous roads increases resistance and fuel consumption. Natural wind: Driving against the wind or on windy days increases car resistance and fuel consumption. Low ambient temperature: When the engine block is cold, the injected gasoline is less likely to atomize during cold starts, requiring more gasoline to be injected for combustion, thus increasing fuel consumption. Additionally, at low temperatures, the engine's computer controls higher idle speeds to warm up the car, which also increases fuel consumption.

What is the reason for the display screen malfunction after replacing the car battery?

The reason for the display screen malfunction after replacing the car battery is due to a circuit fault. The detailed causes and solutions are as follows: First, check whether the power supply to the display screen is normal. If the power supply is abnormal, replace the power supply module. Then, check whether the ribbon cable connection is good. If there is a problem, replace the ribbon cable. Check whether the display screen is damaged. Replace the display screen for testing. If it returns to normal, the display screen is damaged. If the power supply is normal and the ribbon cable connection is good, check the video output signal of the motherboard and replace the motherboard for testing. Precautions for replacing the battery: It is necessary to distinguish whether the vehicle battery is a regular battery or a start-stop battery. Accurately identify the positive and negative poles. If there is acid corrosion on the terminals during replacement, it must be cleaned thoroughly. When removing the battery, disconnect the negative terminal first and then the positive terminal. When installing the battery, connect the positive terminal first and then the negative terminal. The terminal clamps must be tightened. Battery maintenance precautions: Avoid storing the battery in a discharged state. A discharged state refers to the battery not being charged in time after use. When the battery is discharged, sulfation is likely to occur, with lead sulfate crystals adhering to the plates, blocking the ion channels, resulting in insufficient charging and reduced battery capacity. When the battery is not in use, it should be charged once a month to extend its service life.

At what speed can cruise control be activated?

Cruise control can be activated above 40 km/h. Cruise control is used to maintain a constant speed for the vehicle. Once the car is set to cruise mode, the engine's fuel supply is controlled by the computer, which continuously adjusts the fuel supply based on road conditions and the vehicle's driving resistance to maintain the set speed without the need to operate the accelerator. Cruise control is also known as a speed control system, autonomous driving system, etc. Its function is to maintain the speed set by the driver without pressing the accelerator pedal, allowing the vehicle to travel at a fixed speed. With this system, drivers no longer need to control the accelerator pedal during long highway drives, reducing fatigue and unnecessary speed changes.
